The questionnaire contains five items comprising questions of thermal and dyses- thesia qualities, evoked pain, paroxysmal pain, and autonomic dysfunction, and two items requiring testing for allodynia and pin prick threshold. The item responses are weighted and the sum score ranges from 0 to 24. A score of 12 or more is the cutoff applied regarding diagnosing a neuropathic pain disorder. At the time the study started, the S-LANSS [30], which is a self-report question- naire of the LANSS, was not available. Hence, the first five items in LANSS were used for the self- reported follow-ups over the 4 months. These five items give a maximum score of 16.
